Materials Science: CG

Model large-scale structural equilibration and evolution to characterize complex systems

Critical phenomena for formulation and chemistry development such as phase separation and liquid structuring can occur at time and length scales that are difficult to access with all-atom (AA) molecular dynamics simulation.

MS CG (Materials Science Coarse-Grained Modeling) is intended for molecular dynamics simulations of larger bulk systems over a more extended period of time than AA models. MS CG provides an infrastructure to draw coarse-grained molecules and map from all-atom to coarse-grained structures automatically, as well as fit and assign coarse-grained force fields.

Key Capabilities

Easily build large systems of interest with flexible, intuitive workflows

  • Sketch CG molecules directly
  • Map all-atom molecules to CG models automatically for MARTINI or dissipative particle dynamics (DPD), or by user specification
  • Efficiently build CG polymers
  • Cross-link molecules in bulk systems
  • Provide different levels of models, from simple models with 10’s of atoms per bead to finer grained models with 2-10 atoms per bead
  • Build complex structures using CG molecules via a diverse set of builders

Improve your molecular dynamics simulation speeds

  • Achieve faster simulations often at near atomic detail
  • Study the behaviors of large collections of molecules extending beyond the typical atomistic simulation time

Perform advanced structural characterization using a broad range of designed tools

  • CG trajectory viewing with the ability to rapidly measure geometric  features
  • Clustering analysis
  • Radial distribution functions
  • Density profiles
  • Free volume analysis
  • Membrane lipid tilt analysis

Predict key properties of systems

  • Access advanced workflows for predicting thermophysical, mechanical, and diffusion properties

Benefit from flexible support and out-of-the-box automation for widely used coarse-grained force fields

  • DPD with support for automatic AA to CG mapping and CG parametrization
  • MARTINI 2.x non-polarizable force field with support for automatic AA to CG mapping and CG parametrization for speciality chemicals and polymers
  • Generalized Lennard-Jones potentials with Coulombic interactions
